PATENT ATTACHMENT FOR LAWN-MOWERS.

sPEcIFIoA no v rea ing part of Letters Patent No. 760,751, dated. May 24,1904, Application filed January 9, 1904. Serial No. 188,331. (No model.) r

To all whom it may concern:

Be it known that I, WILLIAM H. QGDEN, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Attachments for Lawn-Mowers, of which the following is a full, clear, and exact description.

This invention relates to improvements in lawn-mowers and the like, and has for its object to provide means to prevent the lawnmower from slipping when it is being propelled along the side of a hill or terrace, as will be fully described and claimed hereinafter."

In the accompanying drawings, which form a of a lawn-mower. Fig. 3 represents a sectional view of a portion of a traction-wheel, taken on the line 3 3 of Fig. 1. Fig. 4 represents a sectional view of a portion of a trac-,

tion-wheel, taken on the line 4 4 of Fig. 1.

- A lawn-mower that is being operated along the side of a hill or terrace is liable to slip,

which is of course objectionable, and to obviate this objection I provide one of the lawnmower wheels, or both, with sharp projecting portions that are adapted to enter the turf or soil sufliciently to prevent the lawn-mower from slipping sidewise. In the particular construction illustrated these projections consist of spurs l projecting at intervals from the wheel 2 and which it is obvious will enter the soil or turf for the purpose stated.

instances, however, it'would be undesirable to have these sharpened projections on the lawnmowerfor' instance, when it would be transported from placeto place over pavements-- and for this purpose I make these projections removable, and in .the particular instance shown in the drawings, illustrating a preferred embodiment of my invention, these spurs 1 are carried by a member which is conveniently a band or collar 3, as shown inFig. 4, and which collar 3 is adapted to be removably secured upon the wheel 2. The said. collar 3 can of coursebe secured upon the wheel in various ways to prevent accidental disengagement therefrom, as well as to prevent relative rotary movement, and in the particular instance illustrated the said wheel is provided with a groove or recess 5, in its periphery, at the inner end of which is a transverse socket 6. The projection 4 on the collar enters the groove or recess 5 when the collar is placed upon the wheel, and when in position said projection will enter either of the ends of the socket 6,

and thus prevent the rotation offthe collar 1 upon the wheel, as well as accidental lateral movement, It is obvious, however, that the collar may be secured in other ways." For instance, if it weremade to fit tightly or snugly upon the wheel and to be driven thereon and therefrom suflicient friction might be secured .between these parts to hold the collar in place for the purpose intended. "Further, the

transverse socket 6 might be done away with wheels will be prevented from slipping downhill when operated on the side of a hill and will also insure the proper. operation of the lawn-mower when operating upon slippery level ground. I

. Having thus described my invention, what I claim, and desire to protect by Letters Patent of the United States, is

' 1. The combinationywith a lawn-mower wheel, having a peripheral recess extending inwardly from one side of the wheel and partially across the same, of a collar fitting tightly around said wheel, and adapted to be held in place by friction, said collar having an interior projection, situated within said recess, and exterior projecting portions upon said collar.

2. A combination with a lawn-mower wheel, having a peripheral recess extending inwardly from one side thereof, and partially across the wheel, and communicating with a transverse socket at its inner end, of a collar fitting tightly around said wheel, and adapted to he held in place by friction, said collar having I5 an interior projection, adapted to enter the open end of said recess and to pass therethrough to and into said socket, and exterior projections upon said collar.

In witness whereof I have hereunto set my 20 hand this 31st day of December, 1903.

YVILLIAM H. OGDEN.
